1. /MODUNLOAD causes cores: |
5 |
- If a module is modified before being unloaded, /MODUNLOAD (and |
6 |
therefore /MODRELOAD) may cause a core. |
7 |
|
8 |
This problem is caused by the behaviour of the OS, which treats |
9 |
shared libraries differently to executables (modifying the ircd |
10 |
binary whilst it is running would also cause a core, but is denied |
11 |
by the OS). There is no way to fix this at the application level, |
12 |
and fixing the OS to do the right thing is also difficult. |
13 |
|
14 |
A workaround to avoid coring is possible however. To install new |
15 |
modules, first remove or rename the old module, then copy/move the |
16 |
new file into place. /MODUNLOAD will then work successfully. |
17 |
|
18 |
Alternatively, running ./configure with the --disable-shared-modules |
19 |
argument will link all the commands statically, losing the advantages |
20 |
of upgrading at runtime, but reducing the chances of accidentally |
21 |
coring your server. |
22 |
|
23 |
2. Solaris stock 32bit stdio is limited to 256 fds. This breaks when using |
24 |
cryptlinks. |
25 |
|
26 |
3. New bug reported in some 64 bit and powerpc (yellowdog linux) code. |
27 |
This bug is actually in gcc itself, the spec says you don't modify |
28 |
a va_list in libc, but gcc does. The bug manifests itself as |
29 |
immediately coring when anyone types anything on a channel. |
30 |
You will find a quick work around in contrib until this bug in gcc |
31 |
is fixed. |
32 |
|
33 |
This is a quick test program |
34 |
libc_vprintf |
35 |
cc -o libc_vprintf libc_vprintf.c |
36 |
./libc_vprintf |
37 |
|
38 |
If the program doesn't core, you are fine. |
39 |
|
40 |
The work around is the vprintf_fix.patch in contrib. |
